2.5 Project data volume and operating conditions
Valid for firmware version V3.1.x of the integrated technology
When you plan your Motion Control tasks, make allowances for the following
project data volume and operating conditions listed.
Project data volume (CPU 317T)
• 32 axes (virtual or physical)
• 32 cams
Eight cams can be output as "high-speed cams" at the integrated outputs of the
Technology CPU. A further 24 cams can be implemented via distributed I/O
(ET 200M or ET 200S, for example.) These cams can be integrated as "high-
speed cams" at the TM15 and TM17 High Feature.
• 32 cam disks
• 16 measuring sensors
• 16 external encoders
Note
The maximum number of technology objects (TOs) may not exceed 64. 18 axes,
22 cam disks, 18 cams, 5 measuring sensors, 1 external encoder = 64 TOs, for
example.)
Operating conditions
• The system can be configured using S7-Technology V2.0 and
STEP 7 V5.3 + SP1 or higher.
• All HW components required by the integrated technology must be connected
to DP(DRIVE).
• In the user program, you can address up to 64 bytes of input and 64 bytes of
output data of the integrated technology. Inputs and outputs available:
- 4 integrated inputs of the Technology CPU
The integrated inputs can be used either for analysis functions in the user
program, or for technological tasks. Mixed mode is not possible.
- 8 integrated outputs of the Technology CPU
(exclusive use as with integrated inputs)
- Inputs and outputs of distributed I/O on DP(DRIVE)
• Distributed I/O not required by the integrated technology should preferably be
connected to the MPI/DP interface of the Technology CPU.
• Programming devices, text-based displays and OPs may not be operated on
DP(DRIVE).
• Up to 210 Motion Control commands can be active simultaneously.
• The typical cycle time of technology functions in the user program is 80 µs.
